Abstract: A sitting and reclining cushion is divided into a seat cushion and a back cushion, which are configured in an essentially identical manner. A sleeve consisting of a textile material with low elasticity contains a plurality of tubular pockets consisting of an identical material and joined longitudinally to said sleeve by means of seams. Each pocket is likewise connected to its neighbour or neighbours by means of seams. Each pocket contains a pouch, which consists of an elastic plastic and comprises a valve, and can be filled with compressed air. As a result, the pockets modify their shape, thus tensioning the sleeve and forming the actual sitting or reclining surface. The optimised shape of the cushion structure can be adapted to individual requirements for comfort by means of different air pressures in the pouches.

Abstract: A method and apparatus employing algorithms enabling cellular networks to determine the range of code transmit power in downlink, as well as uplink, power control. Two exemplary algorithms provide a determination of an appropriate transmit power range for each code so that when the transmit power of any code approaches an upper limit, the transmit power of the other codes can be adjusted to catch up with the dynamic range. Even though the two exemplary algorithms have functional similarities, in the second algorithm, the frequency of reconfiguration of code transmit power range is much less than the frequency of change of the number of codes. Both algorithms are applicable for use in all modes of transmission in UMTS systems.
